With the help of hypervisors, businesses can create virtualized environments that enable efficient utilization of hardware resources and provide a robust platform for running multiple operating systems and applications on a single physical machine. Whether it’s deploying virtual servers, desktops, or entire datacenters, hypervisors are key components in modern IT infrastructures.

How does a Hypervisor work?

When it comes to virtualization, the hypervisor plays a crucial role. It acts as the bridge between the physical hardware and the virtual machines, providing a layer of abstraction that allows each virtual machine to function as if it were running on its own dedicated physical machine.

The hypervisor is responsible for managing and allocating various resources to each virtual machine, including CPU processing power, memory, bandwidth, and disk storage space. By effectively distributing these resources, the hypervisor ensures optimal performance and prevents conflicts between virtual machines.

Virtual machines can interact with the hypervisor through API calls, enabling them to access and utilize the allocated resources.
